i'm running a niche website for a very conservative group and one request they have is that we need to make it as difficult as possible for users to save images of other users. i know there is no way to satisfy this requirement 100% but at least i can make it difficult for people to save images off the site.

The only thing i've done so far is disable right-clicking on images (via jquery), I've also put in blocks for hotlinking. Is there anything I could do towards this requirement ?

thanks in advance.

You cannot disable copying/saved since people could view your source which would lead onto the image directory. Also users can be able to simply print screen your website, therefore saving your image. If you do not want users to save your images, then don't add it online.

你不能。我认为无需右键单击即可保存图像的人不会再受到任何困扰。

如果您创建一个 Flash 文件并在 Flash 中显示图像，则可能会更难。如果您想使用普通的 img-tag 显示图像，那么 Justin 的评论说明了不下载图像并同时显示它的悖论。

这是邪恶的，但你可以继续清除剪贴板

可能会使计算机在页面上时无法使用。

另一个想法是在图像上放置元数据或水印，以识别哪个用户获取了副本。然后，如果您在野外找到图像，您就可以弄清楚是谁做的。如果有限制复制的服务条款，您就会知道该向谁投诉。
